Final answer:
A rescue course of prednisolone for an asthma attack is used when symptoms are not controlled by first-line inhaled bronchodilators. It is used for severe exacerbations and based on individual patient plans developed with healthcare providers.
Step-by-step explanation:
A rescue course of prednisolone for an attack of asthma should be initiated when a person experiences symptoms of an asthma attack that are not adequately controlled by inhaled bronchodilators. These symptoms may include coughing, shortness of breath, wheezing, and chest tightness. In severe cases, symptoms may escalate to difficulty breathing with cyanotic lips or face, confusion, drowsiness, and a rapid pulse. Short-term, fast-acting drugs such as inhaled bronchodilators are the first line of treatment; however, when these are insufficient, oral corticosteroids like prednisolone may be prescribed to decrease inflammation and improve respiratory function.
Prednisolone is often used in the short-term management of more severe asthma exacerbations. The decision to use prednisolone should be based on the severity of the attack, the frequency of asthma attacks, and the patient's response to other asthma medications. It is vital for anyone with asthma to have a clear action plan developed with their healthcare provider, which includes when to use prednisolone as a rescue therapy.
